"We shook on it and everything," Walker said. "I have respect for KG. I know what type of player he is."

After Walker contested Garnett's potential tying jump shot at the end of the Knicks' 106-104 win over the Celtics, Garnett appeared to grab Walker's throat and shove him before the two were separated. An NBA spokesman told the Boston Herald that Garnett will not be fined or suspended.

"It was in the heat of the moment," Walker said of his former Celtics teammate. "We're grown men and emotions run high sometimes and things happen."

Even after seeing the incident replayed on television, he was unsure what provoked Garnett to go after him. "No reason," he said. "It's been playing on ESPN all day, so I'm pretty sure you guys have your own opinion of it. But to me, it's nothing. We won the game and it's on to Golden State."
